HF Cat for a 3.0L

[Frey7190]

Alright so i've listened to your ideas to what I could do to my 3.0L v6, and one comment i got was to install an HF cat... My question to you guys is/are:

- Does an HF cat mess around with my computer?
- Does it make the car any louder?
- What are the Pro's to an HF cat?
- What is the size of an OEM (stock) Cat on the 3.0L


Is this one a good buy?

im gonna say no to the ebay HFC.

I'm not huge on the things anyways... and personally I'd just tell you to get custom DP's w/no cats, a X-pipe, and some maggy's then just call it a day. but that'd be stupid sexy/loud, and everyone within a 10 mile radius of you would be jealous of your car - thus increasing the risk that your ride gets jacked.

really though, unless you're going FI - i dont think there's too much need for HFC's or test pipes on your car...

and yes you'll probably still throw codes like lil wayne spits game
(i.e. - every once in awhile)
